Deep Engraving with Fiber Laser Marker

by Linda MarrJanuary 01, 2019

Fiber laser markers can be operated at different frequency (pulse width) of laser beam. Photothermal effect dominates in long pulse (nanosecond, low frequency), and leads to engraving; photoablation dominates in short pulse (picosecond, high frequency), and lead to ablation or removal of materials. By switching between high and low frequencies, our laser markers can produce deep structures on metals via layer-by-layer removal of materials.
